The general idea is to implement something resembling the GDSII file-format, but with some vectorized element types (eg. circles, not just polygons), better support for E-beam doses, and the ability to output to multiple formats.

Installation

Polygon de-embedding

Maybe

Construct from bitmap
Boolean operations on polygons (using pyclipper)
Output to OASIS (using fatamorgana)
